SHUTTLE-BOX FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 644,958, dated March 6, 1900.

Application filed June 5, 1899. Serial No. 719,380, (No model.)

To aZZ whom it may concern:

Be it known that L'HORACE WYMAN, a citizen of the United States, residing atWorcester, in the county of Worcester and State of ll/lassacl1usetts,have invented certain new and useful Improvements in Looms, of which the following is a specification. V

My invention relates to shuttle-box guides in drop-shuttle-box looms; and the object of my invention is to provide a guide for the inner ends of the shuttle-boxes which is provided with a projecting flange to extend in front of the inner open ends of the shuttleboxes and in front of the ends of the shuttles contained therein, both above and below the level of the raceway, and having a central opening on the level of the raceway through which the outgoing or ingoing shuttle passes, said opening having curved portions which act to guide the outgoing shuttle and to force a shuttle into the box if it does not fully enter the same as the shuttle-boxes are raised or lowered. The projecting lip or flange on the shuttle-box guide, above and'below the level of the raceway, serves to hold the shuttle in the box in its proper position for picking.

My invention consists in certain novel features of construction of my improvements in shuttle-box guides, as will be hereinafter fully described;

Referring to the drawings, Figure 1 is a top or plan view of one end of the lay and shuttle-boxes and shuttle-box guides embodying my improvements, looking in the direction of arrow a, Fig; 2. Fig. 2 isafrontview looking in the direction of arrow 17, Fig. 1; and

Fig. 3 is a vertical section. taken at a point indicated by line 3 3, Fig. 2 looking in the direction of arrow 0, same figure.

In the accompanying drawings, 1 is the lay, and 2 is the lay-sword, having the upward extension 2. To the upper part of thelay-sword is bolted the drop-shuttle-box frame or casting 3 in the ordinary way. At the outer end of the frame or casting 3 is bolted the verti- (sally-extending shuttle-box guide-plate 4, which has a groove r in the inner edge thereof, into which extends a lip 5 on the outer edge of the drop-shuttle-box frame 5 in the ordi- The inner end of the frame or casting 3, between the end of the shuttle-box and the lay-sword, has a recess, into which is fitted the vertically-extending shuttle-box guide 6, secured by bolts, as shown in. Fig. 1, and comprising a platehaving an alining surface between. the face of the reed and the shuttle-box to guide the runningshuttle and alip or flange U, projecting outwardly in front of the inner ends of the cells of the drop-shuttle box, which are in an inoperative position relative to the race of the lay, said lip or flange projecting sufficiently to just cover the tips of any shuttles carried in the cells of the shuttle-box, as shown in Fig. 1.

The lip or flange 6 preferably extends both above and below the level of the raceway, and there is a groove at the inner part thereof to receive and guide a lip 5 on the drop-shuttlebox frame 5, as shown in Fig. 1.

The lip or flange 6 has a central opening 6" therein on a level with the raceway and curved portions or surfaces 7 at said opening, as shown in Fig. 2. Through the opening 6 the ingoing or outgoing shuttle passes into or out of one of the cells of theshuttle-boxes in line with the raceway, and the curved portions 7 act to force the shuttle into the box as the shuttle-boxes are raised or lowered, and the guide lip or flange 6, above and below the level of the raceway, acts to hold the shuttle in the box when the box is above or below the level of the raceway.

At the lower portion of the opening 6" I provide a horizontal shelf 8 upon the inner surface of the guide-plate 6, as shown in Figs. 2 and 3, and on a level with the raceway. This projection 8 is not wide enough to allow of the point of the shuttle engaging therewith as the shuttle-boxes are raised or lowered, but serves to form a support or way for the inner-edge of the shuttle to travel on as it is picked from or into the cell of the shuttle-boxes.

In connection with the shuttle-boxes I use shuttle-binders 9, actuated by springs 10 in the ordinary way.

The advantages of my improvements will be readily appreciated by those skilled in the art.

By placing the guide of the inner end of the shuttle-boxes on the shuttle-box frame and back of the face of the reed, with a lip or flange extending outward from this position far enough to just cover the tip of the shuttles, which are in an inoperative position, I am enabled to leave the whole front clear and free from any danger of entanglement of the several threads of filling extending from the different cells of the shuttle-box to the selvage of the cloth.

It will be understood that the details of construction of my improvements may be Varied somewhat, if desired.

-I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a drop-box loom, a shuttle-box guide for the inner ends of the sh Little-boxes located back of an alinement with the front of the reed, and having a lip or flange projectingin front of the inner ends of the shuttle-boxes, and in front of the ends of the inactive shuttles, substantially as shown and described.

2. A shuttle-box fra'me provided with a recess near the inner end of the shuttle-box, located back of an alinement with the front of the reed,a guide-plate fitted in said recess having a vertical groove for the inner end of the for the inner ends of the shuttle-boxes, having a lip or flange extending in front of the open inner ends of the shuttle-boxes, and in front of the inner ends of the shuttles, both above and below the level of the raceway, and having a central opening therethrough with curved sides or edges for the ingoing and outgoing shuttles, and a horizontal shelf at the lower inner side of said opening, substantially as shown and described.
